      This is really bugging me! Ok, I am new to Pi programming but I have knowledge of a few programming languages and can usually tweak my head around problems but this has really stumped me!

      I turned the PIR sensor away from me to show no movement. When I use “sudo ./test.sh” I get a load of 0’s on the screen displaying no movement. When I wave my hand in front I get a load of 1’s. So its working correctly.

      I setup MMM-PIR-Sensor and change the pin from default to number 7 in the config file. Nothing happens on the screen. It doesn’t switch off when it senses no movement (like its supposed to)

      This is my test.sh code (which works):

      echo "4" > /sys/class/gpio/export
      echo "in" > /sys/class/gpio/gpio4/direction
      
      while true;  do
              trap 'echo "4" > /sys/class/gpio/unexport' 0
              stat=`cat /sys/class/gpio/gpio4/value`
              echo $stat
      
      done
      exit 0
      

      And my config code:

      {
      module: 'MMM-PIR-Sensor',
      config: {
      sensorPIN: 7 
      }
      },
      

      I just know its something simple but I am stumped!

        @TS77UK said in MMM-PIR-Sensor wont do anything:

        echo “4” > /sys/class/gpio/export

        Ignore that! I was looking at the wrong pin map for my model Pi! I should have been in number 4 not 7! As soon as I typed it I realised the answer lol

        Thank you for your time
